Cell Structure and Function

Cell Structure and Function

• Basic Unit of Life: The cell is the basic unit of life.
• Cell Membrane: Controls what enters and leaves the cell.
• Plant Cells vs. Animal Cells: Plant cells have a cell wall, which animal cells lack. Plant cells also have chloroplasts for photosynthesis, absent in animal cells.
• Energy Production Organelle: Mitochondria are responsible for producing energy.
• Nucleus Function: The nucleus controls cell activities.
• Cell Theory: All living things are made up of cells.

Cell Processes and Characteristics

• Cell Membrane Function: The cell membrane is not rigid and allows movement.
• Chloroplasts Location: Chloroplasts are found in plant cells, not animal cells.
• Cell Division: Cells divide to reproduce.
• Prokaryotic vs. Eukaryotic Cells: Differences exist between these cell types. Prokaryotic cells are simpler.
• Cytoplasm: The jelly-like substance inside the cell.
• Cellular Nutrient Uptake: Cells take in nutrients by a process.
• Photosynthesis: Plant cells use photosynthesis to capture sunlight for energy.
• Intracellular Transport: Materials within the cell are transported.

Defining Structures

• Cells Shape: Cells shaped due to cell walls
• Cell Wall Function: Provides structural support and shape.
• Ribosomes: Protein synthesis occurs within the ribosomes, involved in cell function.
• Cell Membrane Role in Homeostasis: The membrane regulates internal environment by controlling what enters and exits the cell.
• Vacuole Function (Plant Cells): Helps regulate water balance and materials.
• Cell Size Effect on Function: Cell size affects a cell's function.

Specialized Cells and Processes

• Stem Cells: Function of stem cells and their importance
• Cell Communication: Cells communicate with each other in various ways
• Impact of Environment on Cell Function: The environment influences cell function.
• Cell Division Impact: Cell division is crucial for growth and repair.
• Organelle Functions: Organelles have specific functions within a cell.
• Cell Energy Production: Cells produce energy, and its importance in cells.
• Prokaryotic Cell Structure: A concise overview of prokaryotic cell structure.
